Title: A method and apparatus for improving the utility of speech recognition
Inventor: BOUCHARD JEAN GUY
IPC: H04M3/42
Filed: 1997-10-21
Granted: 2002-11-19
Abstract: A method and apparatus for improving the utility of speech recognition is described.   The method involves capturing a spoken word, passing the spoken word to a speech recognition  algorithm,   receiving  at   least   one   text representation  of  the  spoken  word  from  the  speech recognition algorithm, and passing a text representation of the spoken word to a display telephone to permit the user to select the correct representation of the voice response.          The apparatus is an access server which communicates with a display telephone,  a  speech  recognition  algorithm which responds to queries from the access server and one or more databases which likewise respond to queries from the access server.  The method and apparatus are particularly useful in automating such functions as telephone directory services using display telephones.   The advantage is the ability to completely automate directory services for owners of display telephones and to significantly broaden the applications for speech recognition as a tool in information retrieval and transaction processing.

Title: Fire suppressant foam generation apparatus
Inventor: SMAGAC DENNIS EDWARD
IPC: B01F5/06
Filed: 1996-05-17
Granted: 2003-10-28
Abstract: The fire suppressant foam generation and application apparatus produces a low moisture content fire suppressant foam for use in fire fighting applications. The reduction in the water content of the fire suppressant foam is accomplished by the use of pressurized gas in place of water along with a stata tube apparatus to agitate the foam/water mixture to create the fire suppressant foam. A pressurized gas operated pump can be used to actively draw the water/foam mixture from a supply tank and supply it under pressure to the stata tube and outlet line.

Title: Heat exchanger
Inventor: TAKAHASHI TSUTOMU
IPC: F28D9/00
Filed: 1996-07-26
Granted: 2003-01-28
Abstract: First heat transfer plates S1 and second heat transfer plates S2 folded along crest folding lines L1 and valley folding lines L2 are bonded to an inner periphery of an outer casing 6 and an outer periphery of an inner casing 7, so that the first and second heat transfer plates S1 and S2 are disposed radiately, thereby forming combustion gas passages and air passages circumferentially alternately. One ends of the combustion gas passages and the air passages are cut into an angle shape, and one side and the other side of the angle shape are closed to form combustion gas passage inlets 11 and air passage outlets  16. In a similar manner, combustion gas passage outlets and air passage inlets are formed at the other ends of the combustion gas passage and the air passages. Thus, it is possible to provide a heat exchanger which has a simple structure and is easy to manufacture, and in which the pressure loss due to bending of flow paths can be suppressed to the minimum.

Abstract: A system and method for automated task selection is provided  where  a  selected  task  is  identified  from  the natural speech of the user making the selection.  The system and method incorporate the selection of meaningful phrases through the use of a test for significance.   The selected meaningful  phrases  are  then  clustered.    The  meaningful phrase  clusters  are  input  to  a  speech  recognizer  that determines  whether  any  meaningful  phrase  clusters  are present in the input speech.   Task-type decisions are then made  on  the  basis  of  the  recognized  meaningful  phrase clusters.

Abstract: An optical fire detector employs two or more sensors operating a different spectral bands. The spectral bands are selected to have approximately coincident cut-off wavelengths in order to make the detector's ability to positively identify a fire more uniform over its field of view. The use of three overlapping spectral bands provides the detector with enhanced detection capabilities for large, hot fires that behave like black body radiators.

Title: Proof that contraction of the calf cannot increase pressure on the pedal and mechanisms for exploiting this basic discovery
Inventor: JACQUES ANDRE
IPC: B62M1/36
Filed: 1999-10-25
Granted: 2007-06-12
Abstract: In order to understand the invention, it is necessary to BEGIN by understanding IN DEPTH the following DISCOVERY which relates to the calf during pedaling;  the entire world is misled by two OPTICAL ILLUSIONS (figs. 21 and 22 symbolize a lower member pressing down upon a pedal, 6 is the thigh, 11 the leg, A+B the foot and 1 is the ankle). The first ILLUSION (fig 21) is to believe that the calf (M) INCREASES the pressure on the pedal. The second ILLUSION (fig 22) is to FAIL to  see that the force M is CANCELLED OUT by the force M'. The total amount of pressure on the pedal is derived from the THIGH EXCLUSIVELY, whereby the contraction of the CALF is a loss of energy. The aim of the invention is to REPLACE the pedal by a mechanism which AVOIDS THE USE OF THE CALF, thereby enabling performance to be MULTIPLIED BY TWO WITHOUT incurring A LOSS OF POWER!
